1 Claim.

My invention relates to hinged rod-joint locking devices.

Included in the objects of my invention is a novel hinged rod-jointlocking device adapted for steady and smooth release when used tosupport heavy objects in cantilever fashion.

With the above and other objects in view, as may appear hereinafter,reference is directed to the accompanying drawings in which:

Figure 1 is a top plan view of a common vise with my hinged rod-jointattached to the anvil or mounting bar.

Figure 2 is a side elevational view thereof with one form of themounting socket shown in section and indicating by broken lines variousadjusted positions of the vise jaws;

Figure 3 is an enlarged fragmentary sectional view taken through 3-3 ofFigure 4;

Figure 4 is a sectional view taken through 4-4 of Figure 3;

Figure 5 is a fragmentary sectional view taken through 5-5 of Figure 4;and

Figure 6 is a sectional view of a modified form of the socket membershowing the mounting post fragmentarily.

My universal vise includes a socket member I which, as shown in Figure2, may be adapted for mounting on the underside of a table. In this casethe socket member is provided with a flange 2 adjacent its open end.Alternatively the socket member may be provided with a flange 3 at itsclosed end so that the socket member I may be mounted on top of aworktable as shown in Figure 6.

The socket member is adapted to receive the cylindrical lower portion ofa post 4. The portion of the post 4 which fits within the socket I isprovided with a groove 5 and a suitable setscrew 6 extends laterallyinto the socket member for the double purpose of restraining the postagainst removal and to secure the post against rotation in the socket.

The upper end of the post 4 is enlarged to form a head I having a.lateral opening adapted to receive a longitudinally split bushing 8. Oneend of the bushing is provided with a flange 9 to restrict movement ofthe bushing through the opening in the head 1. The bushing 8 is providedwith a bore l having a beveled end. H. The opposite end of the bushingis provided with tapered sockets 12 on opposite sides of the bore l0 andcentered between the split halves of the bushing.

An anvil bar I3 is provided from which extend a pair of laterallydirected wedge pins [4 adapted to fit the sockets l2. Between the wedgepins [4 there is provided a screw-threaded hole which receives thescrew-threaded end of a stem I5. The stem l extends through the bore illof the split bushing and is provided with a knur head or handle l6.Journaled on the head I6 is a wedge cone I! which enters the beveled endll of the bushing bore Ill.

The anvil bar I3 is provided at one end with a fixed vise jaw l8 offsetfrom one side of the anvil bar and projecting forwardly of the anvilbar. A boss I 9 laterally projects from the opposite side of the anvilbar. A movable jaw 20 confronts the fixed jaw l8 and includes adepending portion in which is fitted a pair of guide bars 2| adapted toextend into the anvil bar and into the 7 boss l9. Between the guide bars20 is mounted a vise screw 22 which extends through the boss portion IS.The outer end of the vise screw is provided with a, suitable handle 23.

The anvil bar may be rotated about the horizontal axis defined by thestem l5 through the various positions shown in Figure 2.

Having fully described my invention, it is to be understood that I donot wish to be limited to the details herein set forth, but my inventionis of the full scope of the appended claim.

I claim:

A hinged rod-joint locking device comprising: a mounting bar; a mountingpost offset to one side of said mounting bar; means for adjustablysecuring said mounting bar to said mounting post about an axistraversing both said mounting post and mounting bar, said meansincluding a bushing split along a plane including said axis andjournaled in an aperture in said mounting post, a headed stem extendingtherethrough and screw-threaded into said mounting bar, a. pair of wedgepins anchored into said mounting bar on opposite sides of said stem andhaving conical REFERENCES CITED The following references are of recordin the file of this patent:
